CF 105796B - Quadrados consecutivos

The problem gives a very large positive integer written as a decimal string, potentially up to a million digits long. The task is to compute the difference between the squares of two consecutive integers: if the number is $n$, we must output $(n+1)^2 - n^2$.

CF 105796C - Algoritmo de Euclides

The task is to count how many iterations are executed by a slow version of the Euclidean algorithm. The algorithm starts with two positive integers. While the two values are different, it repeatedly subtracts the smaller value from the larger value and increments a counter.
